# Chapter 5 - Section 5.1 - Exponents and Scientific Notation - Exercise Set: 130

$.0668$ square kilometers

#### Work Step by Step

We are given that Hagerman Fossil Beds National Monument in Idaho contains $6.68\times10^{-2}$ square kilometers of privately owned land. Since the exponent is negative, move the decimal 2 places to the left. Note that 2 places to the left will be 1 decimal place past the first digit (6), so we will add 1 zero before 6. $6.68\times10^{-2}=.0668$ square kilometers
